Specification of Letters Patent.

Patented Mar. 4, 1919..

Application filed. m a1, 1918. sari-i1 No. 247,661.

To all whom it may concern:

Be it known that I, FINIs J. HENDERSON, a citizen of the United States, residing at Moreland. in the county of Pope and State of Arkansas, have invented certain new and useful Improvements in Door-Checks, 'of

which the following is a specification.

This invention relates to door checks, and the object thereof is to construct a simple and eflicient device of this character which will effectively hold a door 'or gate in open position until released.

Anotherobject is to provide a check of this character with means for releasably holding the surface engaging member out of operative position when'not desired for use.

With the foregoing and other objects in view, which will appear as the description proceeds, the invention resides in the .com-' bination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made Within the scope of what is claimed without departing from the spirit of the invention.-

In the accompanying drawings Figure 1 represents an edge view of a portion of a door showing this improved check applied, and in side elevation, the surface engaging member thereof being in operative position in full lines, and in inoperative position in dotted lines.

Fig. 2 is a front elevation of the check detached,

Fig. 3 is a side elevation showin the chrack applied and in inoperative position, an

Fig. 4 is a detail perspective View of the surface engaging member and its connecting par In the embodiment illustrated the check constituting this invention is shown applied to a door D and comprises a plate 1 here shown rectangular in form, although obviously it may be of any desired configuration. This plate 1 has a plurality of laterally projecting apertured ears 2 for connecting it to the outer face of the door or ate in connection with which it is to be used.

This plate 1 has its lower end rolled to form a bearing or knuckle 3 for hinged or pivotal connection with the plate of the surface engaging member 5. This member 5 is composed of a single piece of wire bent into rectangular form with the cross bar 4 at one end mounted in the bearing 3 and forming a journal for the member'5, while its other cross bar 4: is designed to be engaged by a spring catch presently'to be described.

One side member of the member'5 is extend- T ed longitudinally at one, endto form an arm 6 having a penetrating spur 7 at its free end, said spur being turned laterally and. pointed to facilitate its engagement" with the floor or surface when the door or gate is to beheld open by said device. The crossbar 4' has its free end looped to form an eyed which encircles the-side member of the surface engaging element 5 which carries arm 6.

The upper end of'platel is also rolled to form a bearing 15 in which is mounted a pintle 16 carrying-thereon at its opposite ends beyond said bearing 15, apertured lugs 14 which project upward from one arm 8 of a latch 10. This latch 10 which is sub stantially L-shaped,the ears or lugs 14 of which are disposed adjacent the juncture of its arms, is designed for locking the member 5 in inoperative position. The arm 10 of this latch is in the form of a plate overlying plate 1 and having an aperture in its free end through which extends a stud 11 which projects laterally from plate 1 and has a coiled spring 12 mounted thereon between the outer-face of arm 10' and a washer 13 secured to the outer'end of the stud 11 by any suitable means, a nut 13' being here shown for this purpose. This spring 12 exerts its tension to normally force arm 10 flat against the plate 1 and to hold arm 8 in normal locking position. This arm 8 has a downward offset 8 with its free end flared upwardly as shown at 9 to facilitate the passage thereunder of the cross bar 4: of the locking or surface engaging element 5. This flared end 9 also is designed for engagement by the user to release said cross bar, the thumb of the user being placed thereunder and on swinging the member 10 on its pivot 16 the free end of its arm 10 will move outwardly against the tension of spring 12 and thus release the member 5 and permit it to be swung downwardly into the position shown in Fig. 1, whereby the penetrating spur 7 thereof will operate to lock the door D against movement.

When it is desired to release the member 5 from the floor or other surface, the door is 7 swun npwardly into the dotted line posi tion s own in Fig. l, the cross bar 4" snapping under the offset 8 in the arm 8 of the latch 10.

WVhile this device has been shown and described as applied to a door, it may be obviously equally-we'll applied to a gateorany other swinging object of thischaraeterx The foregoing description and the drawings have reference to what may be considered the preferred or approved form. of my invention It is to be understood that. I

I maymake such changes in construction and arrangement and combination of parts, materials dimensions, etc.,, as may prove expedient and fall within the scope, of the claimed invention. v

Having thus fully describedmy invention,

' what I claim. as new and desire to secure by Letters ,Batent, is.:-'- I iheA'door; check comprislng a plate having attaching means, an L-shaped latch pivotally mounted on said (plate at. the'junotion oi the arms,- one of sai arms of saidlatcli overlying said plate, a spring mounted to hold said armnormallyin. contact with, said plate, a surface en aging member pivotally 'mounted on said p ate and having a lateral extension-ionreleasabl'eengagement by said latchto hold said swinging member in inoperative position.

2. A door check comprising a plate having its opposite ends rolled to fermsbean ings Vandiprovided, at its side edges with 51-011, for: releasable engagement by said spring pressed; catch whereby said element isw held ininoperatlve position.
